of an improved device for supporting the pipes intermediate their ends.

Referring more particularly to the drawings, and in which similar reference-numerals designatethe same parts throughout the several views, the numeral '10 designates a drying chamber or casing of any suitable size and shape, preferably in the sha e of a cylinder, having its respective en s closed b means of headers, (designated generally by the numerals 11 and 12.) Each of these heads is provided with a centrally-dis ose d chamber or compartment,'(designate respectively,

by the numerals 13 14,) each having a cap or I cover 15 16,, respectively, secured in-position inany suitable manner.

. Extending or radiating from the chamber or com artment 13 in the header 11 are hollow spo es or passages 17 which 0 )en into or communicate with an annular c amber or compartment 18, arranged adjacent the periphery of the header and concentric-with the 1 chamber or compartment 13. (See Fig. 5.) The header 12 is also provided with an annular chamber 19, arranged concentric with the chamber or compartment 14, and 20 designates hollow spokes or passages radiating.

arranged with relation to each other that each of'the compartments in the annular chamber 19 formed by the partitions 21 has communicating therewith apassage 20 and 22.

. Located within the compartment 14 and opening through the cap or plate 16 thereof is a supplemental chamber or compartment 23, and 24 deSignates'shQrt sections of tubes or pipe, which. are tapped through the wall of the chamber or com artment 23 and-the adjacent closed end 0' the passages 22 of the chamber 19, thereby forming a communicating passage between the two compartments or c ambers 19 and 23. There may be one of these tubes em loyed for each of the passages 22, and sai tubes. are.held or secured in place many suitable manner.

IOO

the chamber 23 and into the compartment or chamber 142, and 26 designates partitions arranged within the chamber 23 and between the wall thereof and the pipe 25, thereby forming a plurality of compartments. One end of this chamber is open and communicates with a tube or pipe 26, which preferably surrounds the supplyepi e and is provided with a drain-pipe 27, l eading there from.' r

The headers 11 and 1 are connected by a plurality of series of pipes 28 29 30. (More clearly shown in Fig. 3.) The series 29 are arranged concentric with the series 28 and connect the peripheral chambers 18 and 19,-

while the series 30 connect the centrally-disposed chambers or compartments 13 and 14. The series 28 and 29 may comprise any number of pipes; but the number of pipes in the series 29 is preferably considerably less than the number in the series 28 and are preferably arranged in pairs, so that each pair will stand adjacent one of the passages or open ings 2O 22. This arrangement will cause the two series to be formed into a pluralityof separated groups of pipes, with some of the pipes of to outer series intermediate the groups.

The drying chamber or casing 10 may be provided with a lining 31, of wood or any other suitable material, to protect the same against corrosion or the corrosive action of acids contained in the material to be dried. Suitable blocks or supports 32, (see Fig; 8,) held in position in any suitable manner, are disposed between each of the pipes 28 and the wall of the chamber or casing 10, against which the said pipes rest.

The pipes 29 may be supported intermediate their ends by means of blocks or supports 33, standing between said pipes and the ad jacent pipes of the series 28, anda suitable bar or rod 34, engaging the adjacent pipes 29, extends across and rests upon the adjacent pipes 23. A band or strap 35 surrounds'the pipes in each group with its ends secured in any suitable manner to the drying-chamber 10, and said band or strap also serves as a means for preventing displacement of the blocks or supports 33 and the bar or rod 34. The pipes of the series 28, which are located intermediate these groups, may also be spaced from the wall of the drying-chamber by means of the blocks 32, and similar bands or straps 35 surround each of the pipes and have their free ends secured to the dryingchamber wall. Secured between each two of the pipes 28 are plates or shields 36, which are preferably curved and located between the blocks or supports 32 and serve as a means to form a dead-air space to prevent undue radiation of heat and also to prevent the material from accumulating "in the corners formed by the blocks and the wall of the stares chihnlbel or between thepipes 28 and the we A. series of pipes or tubes 37, having one end thereof secured to and communicating with the,compartment or chamber 1 1-, are arranged within the series 30 and terminate short of .the opposite end of the dryingchamber 10. These tubes or pipes 37 are connectedat their free ends by means of a header 38, which is preferably provided with a movable cap or cover 39, and said header is provided with a plurality of ribs or partitions 40, each of which is located between the ends of two of the pipes 37 and serve as a means for evenly distributing the steam. The periphery of this header is recessed or provided with a plurality of seats 21, in which the pipes 3.0 rest, and said. header serves as an additional support for the pipes 30. A band 42, preferably seetional in construction, surrounds the series of pipes 30 at a point concentric with the header 38, and said ring serves as a means for supporting the header to prevent strain in the pipes 30 and is held in position by means of rods or bars 43, one end of each of which is secured to the wall of the dryingchamber 10 in any suitable manner and the other end being connected to the ring 12.

A plate 44 (see Fig. 1) is provided with a plurality of suitable apertures, through which the pipes 30 and 37 ass. This plate. is located at any desire point midway of the ends of the pipes, serving 'as an additional means for supporting said pipes, and this plate is secured in position in any suitable manner, preferably by means of rods or bolts 45, one end of each of which is secured to the plate 44 and the other end to the wall of the drying-chamber.

A suitable tube or conduit 46 projects through the header 11 in a direct line with the header 38 and into the space formed between the two headers 11 and 38. This tube is provided with a hopper 47 and an opening 48 at the opposite end, through which the material is discharged into the chamber 10. Mounted within this tube 46 is a conveyor 49, preferably in the 'form of a screw or auger. The diameter of the tube 46 is smaller than the diameter of the opening in the header 11, through which the tube passes, in order to provide a space or passage 50, through which the vapor generated in the drying-chamber 10 will pass into a supplemental or vapor chamber 51 and out of the stack 52. This chamber 51 may be supported by the tube 46 in any suitable man-- Her and disposed between the header 11 and the said chamber 51 is a sleeve or collar 53, which is secured to the header 11 and has a flanged bearing 54 with the chamber 51 to permitthe drying-chamber to revolve and yet prevent the escape 'of the vapor. The drying-chamber 10 may be supported by IIO any suitable means, such as antitriction rollers or bearings 55 and flanges ortracks 55 and on the desired angle of inclination. A rotary motion may be transmitted to the chamber in any well-known manner, such as a peripheral gear 56 and a pinion 57. Arranged adjacent the discharge end of the cylinder is a casing 58,into which the dryingchamber discharges, and disposed between the chamber and this casing is a collar'or sleeve 59, having flanged connections, and within the casing 58 is a discharge conveyer or chute 60, which conveys the material to any desired point or receptacle. Suitable hand-holes may be provided wherever the necessity may require to permit the parts to be cleaned.

The operation of this apparatus is as fol lows: The heating fluid, which in this exemplification of the invention is steam, is admittedby means of the supply-pipe 25 and discharged into the compartment or chamber 14 in the header 12. From there a portion passes through the pipes 30 37 and into the header 38. The rest of the steam passes through the pipes 30 and into the compartment or chamber 13 in the header 11, up

through the passages 17, into the annular or peripheral chamber-18, back throu h the two series of pipes 28 29, and into t e respective compartments forming the annular chamber 19 in the header 12. Owing to the inclination of the drying-chamber 10, the Water of condensation formed in the tubes will drain toward the header 12 and will be collected in the passages 22, from where it passes through the tubes or pipes 24 into the chamber 2-3, through the tube or pipe 26, and out through the drain-pipe 27. The water of condensation formed in the tubes or pipes 37 will be discharged into the compartment 14, passing through the assages 20 into the chamber 19, and t ran out through the passages 22 and pipe 24 in a similar manner. A rotary motion is transmitted to the drying-chamber, and the material to be dried is fed into the hopper 47 and forced through the tube 46 by means of the auger 49, out through the opening 48 in the tube into the space Within the drying-chamber between the headers 11 and 38. The material falling to the bottom of the chamber as it is discharged from the tube 46 will be caught by the pipes 28 29 and the shields or plates 32 and carried upward toward the top of the chamber as the latter revolves. The material falls as it reaches a point near the top of the chamber and in its descent strikes the pipes 30 37, some. of the material pass- .ing around and some of it between the pipes.

Theangle of inclination of the chamber will cause the material to advance from the feed to the discharge end thereof where it enters the chamber or housing 58 and'is conveyed therefrom by means of the conveyer 60. It

will be seen that by this arrangement the pipes are so arranged as to produce the greatest heating-surface and that they are so distributed as to provide spaces therebetween, through which the material passes, thus greatly increasing the efficiency and insuring a perfect drying of the material. The vapor formed or generated by the wet materialcomin in contact with the heated pipes will pass t irough the space 50 between the tube 46 and the wall of the aperture in the header 11 into the chamber 51 and out through the stack 52.

It is to be understood that it is not desired to be limited to the exact construction or arrangement of the several parts, as various changes may be made therein without departing from the spirit of the invention.
